.To all whom it may concern:

Be it known that 1, CHARLES FRANCIS JENKINS, citizenof the.United States, re-

siding at Washington, District of Columbia,

loosely engages theloop 21 attached to the plunger 22 above which is the spring 23.

The shaft 15 being means which'will the pump will ,operate tocharge the reservoir 7 with a.rproperlymixed"gas drawn from the c arbureter manifold. When the pressure in the reservoir has reached-a pre determined point, say, .twenty-fifve pounds, the plunger 22" raises holding "the checkvalve 19 off its seat, andjthis stops the effor Internalprovements in Starting Devices the follow- Combustion Engines, of which ing isa specification. v This'invention relates to that class of defor starting internal-combust-ion' engines, is primarily intended for automobiles, and has for its main object the employmentof mechanisms which will permit theengine beingstarted from the seat a further increase'in in the reservoir. The distributer- 14 being also attached to the shaft 15 is rotated in time with .the crank-shaft'of the engine, and as the cut-away portion 14* of the'valve uncovers two of the pipes 10 leading to the cylinders, the gas has an open passage from the reservoir through the pipes .8, the valvespace 1 1 cylinders when the hand-valves 11 are opened. The cylinders then quickly fill to a pressure equal to that in the reservoir and then the hand-valves are closed, by a turn of the handle-'12." If now the-charge above the piston which is inproper position is exploded by a touch of the sparking button (with some form of'which practically every automobile --is nowfitted) the piston is driven downward. sion in'the othercylinder, immediately following which the takes up, its regular cycle of operation.

Whether the piping 10 is arranged as shown'in the drawings orin some other way is immaterial, theonly essential being that the pipes leading to the two cylinders in which the inlet or the exhaust ports are open shall be closed bythe valve 14.

hat I claim, therefore, is-f The combination with a seriesv of en- 'ofturnin'g-over the engine,'or the com plicated devices employed when compressed air is. used for the purpose.

Simply I stated, the method employedmore of the engine cylinders with a. combustible mixture which can readily be exploded by means of the ignition devices now on' the engine, thus putting theengine into In the drawings, Figure l-is a top view of the pump and distributing mechanism; Fig. 2 adistributing valve; Fig.3 another view of the same; Fig. i a sectional view of the 5 a diagrammatic view of the assembled device.

In all the figures like symbols refer to like parts, in whicha 1 is a carburetor, of any sultable type for to form an explosive compound; 2*tlie m-aniv fold connecting the carbureter withthe sev eral cylinders of the engine; 3 a pipe leading from the-manifold, past the check-valve From the pump a similar" pipe. leads past the regulating-valve G to the reservoir 7. This pipe has a. branchS leading to the distributing-valve S). From this distributer pipes 10 lead one each to each of 5 the cylinders A, B, G, and D, through the valves 11 which are controlled by thehandle 12, located" within reach of the driver.
